The one head finally gave up last night, I siphoned out what I could. There are still some parts left that'll probably be taken up by the flow it's near. I just didn't want anything rotting or worse yet infectious floating around the tank. The coral itself doesn't seem to want to take in food at the moment, so I'm just watching water quality and keeping an eagle eye on the rest of the coral.
Did I mention I spent hours cutting and fitting foam around the back rim to block the rear chambers, lol. My pearly seems to have accidentally found out there is neat rock rubble and LED lighting back there, lol. The weird..."mod" seems to have worked for now, lol.
